This invention relates to machines for decorticatinor fiber-containing foliate plants of two sets of conveyors arranged in staggered relationship and consistlng of endless ropes which carry the leaves or plants to be'decorticated into and out of the zone of treatment. It is usual in this kind of machine to mount the rope sheaves of the two sets of conve ors upon the same shaft, with the result that when it is desired to place in position or to interchange the end# less ropes, such operation is not only troublesome but also entails a considerable loss of tim@ The shaft carrying' the two rope sheaves is usually separably coupled to a worm'gear adapted to drive the shaft, which shaft must first be lifted from its bearings in order that the ends of the shaft may be exposed, to enable .the endless ropes to be removed or to be placed'in position.` Conse- ,quently, both sheaves must be dismounted even when it is only a matter of replacing the rope of one sheave. The object of the present invention .is to provide an improved machine in which the above mentioned disadvantages do not exist. c

In accordance with the invention twoad-A Cjacent driving sheaves are mounted upon the free projecting ends of separate shafts coaxially arranged, means being provided whereby the driving sheaves may be coupled to and uncoupled from each other. The coupling of the sheaves may, for example, be effected by means of one or more bolts or the like adapted to pass through each sheave.

In order that'the said invention may be clearly understood and readily` carried into effect the samewill now be more fully described with reference to the accom evadrawingwherein- Fig. 1` shows a lsi e tion of a machine incorporating said invention,

Fig. 2 is a plan view of the machine, and Fig. 3 isa detailed sectional view f one form of the invention.A

Reference numerals 1 and 2 indicate the rope driving sheaves of two sets f conveyors 8 and 9 of a decorticating of known 11 cooperate x- The foregoing ecortica Y an typewith thesemgnveyors. The

sheave l is rigidlyv mounted upon the free projecting end of a shaft 3 while the sheave the bolts in a circle near theperiphery of the sheaves. -Whenit is desired to exchange or place in positiona rope in either set of= the'l conveyors all that is necessary is to uncouple the two sheaves 1, 2 bywithdrawing the bolt or bolts 7. Due to the journalling of the sheaves' 1,2, upon separate shafts 3 and 4 it is at once possible to effect this operation without the necessity of removing the shafts from their bearings. l

What I claim is 1. Ina decorticating machine, a plurality of sets of laterally displaced conveyors comprising a driving sheave for each conveyor,

discreteshafts for said sheaves arranged coaxially with each other, driving means for one of said shafts, and detachable coupling means between said sheavesfor transnntting the motion of said one shaft to the adjacent sheave. l

2. In the combinationclaimed in claim 1 `wherein said coupling means comprises one or more bolts engaging said sheaves.
